Fixture ID

The MAC Viper Wash lets you set a four-digit ID number to ease identification of the fixtures in an
installation. When a fixture is powered on for the first time, it displays its DMX address by default. As soon
as you set an ID number other than 0 in FIXTURE ID, the MAC Viper Wash will display this ID number by
default, and indicate FIXTURE ID in the display.

Personality

The MAC Viper Wash provides several options that let you optimize the fixture for different applications in
the PERSONALITY menu:
• The PAN/TILT menu lets you swap and/or invert pan and tilt.
• The SPEED menu lets you set PAN/TILT to NORMAL, FAST (optimized for speed) or SLOW (optimized
for smooth movement – useful for slow movements in long-throw applications). Likewise, you can select
an overall speed for all the effects by setting EFFECT speed to NORMAL, FAST or SLOW. You can also
set effect speed to FOLLOW P/T, in which effects will always use whatever speed is set for pan and tilt.
• DIMMER CURVE provides four dimming options (see Figure 3):
DMX %
Linear
- LINEAR – (optically linear) the increase in light intensity appears to be linear as DMX value is
increased.
- S-CURVE – light intensity control is finer at low levels and high levels and coarser at medium levels.
This curve emulates the RMS voltage dimming characteristics of an incandescent lamp such as the
tungsten halogen lamp of the Martin™ MAC TW1™.
- SQUARE LAW – light intensity control is finer at low levels and coarser at high levels.
- INV SQUARE LAW – light intensity control is coarser at low levels and finer at high levels.
• FOCUS TRACKING sets focus to automatically switch between the three zoom/focus settings when you
use the zoom effect (see "Zoom/focus linking" on page 5).
• AUTO LAMP ON gives three lamp strike options:
- When set to OFF, the lamp remains off until a "lamp on" command is received via DMX.
- When set to ON, the lamp strikes automatically after the fixture is powered on.
- When set to DMX, the lamp strikes automatically when the fixture begins to receive DMX data, and
lamp power is shut down 15 minutes after the fixture stops receiving DMX data. Automatic lamp strikes
are staggered to prevent all lamps from striking at once. The delay is determined by the fixture address.
No matter what the AUTOMATIC LAMP ON setting is, the lamp can be struck by sending a lamp on
command via DMX on the Fixture control/settings DMX channel.
• DMX LAMP OFF and DMX RESET define whether the lamp can be powered off, or whether fixture or
individual effects can be reset by sending a DMX command on the Fixture control/settings DMX channel.
If either of these settings are set to Off, you can override this setting and cut lamp power or reset effects
by applying a special combination of DMX values (see "DMX protocol" on page 19).
• EFFECT SHORTCUT determines whether the color wheel in the MAC Viper Wash DX takes the shortest
path between two positions (shortcuts enabled), crossing the open position if necessary, or always avoids
the open position (shortcuts disabled).
• DISPLAY offers the following options for the LCD display:
